Just give it to me straight...

Yesterday I went in for my first scan. I was suppose to be 7 weeks 6 days. My doctor did a transvaginal ultrasound and said I was only 6 weeks 1 day. She said not assume the worst, but my periods are always consistent and highly doubt I ovulated later because my husband and I only had sex the week I was ovulating. She told me to come back next week and will see if the baby has grown. I am not naive, so I really wish I would have just asked her what the odds are. So I guess I’m asking you guys.. what are the chances this is going to turn out okay? Thanks❤️
